Mentoring a beginner in the I/B tournament, almost all in 4♥+2 here (I sneaked 4♠+3 on a clubs lead).
Not an easy hand to bid at any level, at least playing 2/1.
How would it have gone with your usual partner and opponents?

Indeed a tricky one

I have two potential approaches
1. playing transfers over 1♠-1N
2♣ would be
a) 5x4x limited
b) 5xx4 strong
c) 52x4 limited
d) 55xx invitational
Two issues
a) 1N is non-forcing opposite a balanced hand
b) a simple preference for 2♦ may be too weak
Now opener has space to show shape and after 4♥ the onus is on opener to move forward.

Edit: 1b playing a non transfer approach after 2♣, 2N shows 55 in the unbid suits, then 3 & 4♥ again with the onus on opener to make the slam try. The use of 2N is one of those benefits I find not playing a 2/1 game forcing approach.

2. 2♦ 5♥ 10+, or 6♥ 8-10
Given the shape I favour this approach despite the weak hcp. Again shape can be established, but here a slam move is more likely.

I doubt I'd end in ♠

t would be ugly any way any normal player would bid it, next

Possible

1S-1NT
3NT-then. .

Maybe 6H?

I am biased seeing the hands
